The Landfill Group announces commercial operation of the first RNG project in South Carolina

Read Time: 3 mins

Landfill gas, a natural byproduct of the decomposition process of waste, is collected at the Twin Chimneys Landfill and converted into RNG. The processed landfill gas is injected into the local natural gas system, which is owned and operated by the Greenwood Commissioners of Public Works.

According to the EPA, the environmental benefits associated with this project at full build-out will be equivalent to reducing the CO2 emissions of more than 66 million gallons of gasoline each year.

“The Twin Chimneys RNG project would not have been possible without the tremendous support and leadership of local government, notably Greenville County, Greenwood CPW, and the City of Greenville,” said William Brinker, managing director of the Landfill Group. “TCPP represents a multi-million-dollar investment in the region and the collaboration of local government leaders helps ensure this project will have a significant positive impact on the community, both environmentally and economically.”

The Twin Chimneys project is Enerdyne’s second renewable energy project in Greenville County and follows the success of the Enoree Landfill project, which has been operating since 2008. That project, which won the EPA’s 2008 Power Project of the Year award, utilizes landfill gas to fuel a generator, creating renewable electricity which serves customers of the local electric utility.

Jeff Meredith, general manager of Greenwood Commissioners of Public Works, said, “We are excited to be a part of the first project to deliver renewable natural gas from a landfill to a local distribution pipeline in the State of South Carolina. The project has been operational since late March 2023 and delivering stable and reliable gas into GCPW’s system. This project has truly been a collaborative effort between Greenville County, TCPP, and Greenwood CPW to make a positive impact on the environment and provide value to the customers we serve.”

U.S. Energy, a leading provider of refined products, alternative fuels, and environmental credits, was selected as Twin Chimneys’ compliance and credit generation project partner. With over 40 established RNG pathways with the EPA, the California Air Resources Board, and the Oregon Department of Quality, U.S. Energy is managing the project’s participation in clean fuel programs—handling all registrations, reporting, and ongoing compliance requirements. They have worked within the RFS and LCFS environmental commodity markets since their inception—transacting credits across all fuel types. In addition to their 40+ RNG Development projects they have 50 compressed natural gas fueling stations, more than 100 RNG delivery points, and four thermal energy supply projects.

“Seeing this project reach operational efficiency is a huge milestone for the renewable natural gas community,” said Bryan Nudelbacher, vice president of business development at U.S. Energy. “There is a continued need for more renewable natural gas to come online. We’re thrilled to partner with Enerdyne on this project—helping supply end users with RNG while maximizing the project impact and return.”
